It does report errors, but it does generate the makefiles..
The toolchain file in question is this:

SET(CMAKE_SYSTEM_NAME Windows)

SET(CMAKE_C_COMPILER /opt/cross_win64/bin/x86_64-w64-mingw32-gcc)
SET(CMAKE_CXX_COMPILER /opt/cross_win64/bin/x86_64-w64-mingw32-g++)
SET(CMAKE_RC_COMPILER /opt/cross_win64/bin/x86_64-w64-mingw32-windres)

SET(CMAKE_FIND_ROOT_PATH /opt/cross_win64 /opt/cross_win64/x86_64-w64-mingw32)

SET(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER)
SET(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY)
SET(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)

I did not setup a cross-pkgconfig, can it be the reason? (Don't know how but..)

I guess so.

from libsamplerate.

With autotools, I can set pkg-config path by setting PKG_CONFIG_PATH
environment variable, or I can disable pkg-config functionality altogether
by setting PKG_CONFIG to /bin/false. Is there a similar way to do so
with cmake?

If I am to setup a corss-pkgconfig, how should I set it up in my
toolchain file, i.e. what is the cmake variable name for it?

FindPkgConfig is just wrapper around of pkg-config, i guess you can use all the same tricks. Also you can try PKG_CONFIG_EXECUTABLE.

OK thanks. Closing this one.
